Homework Statement
Find the path of a heat-seeking particle placed at (4,3,10) with a temperature field
[tex]T(x,y,z) = 400 - 2x^2 - y^2 -4z^2[/tex]
Homework Equations
Formulas for directional derivative and gradient.
The Attempt at a Solution
At any point in space (x,y,z), the particle must be moving in the direction which causes the greatest increase in T. This direction is given by the direction of
[tex]\nabla T = < -4x, -2y, -8z > [/tex].
I do not know how to continue from here.
